A process of forming a d-tocotrienol from a (2S)-vinylchromane compound, through hydroboration of the (2S)-vinylchromane to provide an organoborane, followed by coupling the organoborane with a halogenated C-14 sidechain compound under conditions of palladium-catalyzed cross-coupling is taught. Methods for providing the (2S)-vinylchromane compound and the halogenated C-14 compound are disclosed.
